1 Anthropometric Assessment Systems BPK 303

2 Anthropometric Assessments  Comparison of Anthropometric measures to normative data.  Measures intended to reflect growth and/or body composition.  Reliable measurement of standardized techniques essential.  Appropriate norms?

3 C.F.S. - Canada Fitness Survey 1981 Canadian Fitness and Lifestyle Research Institute Canadian Fitness and Lifestyle Research Institute  The 1981 Canada Fitness Survey was the first nationally representative study of the physical recreation habits, physical fitness, and health status of an entire population.  More than 23,000 Canadians aged 7 and older participated in this historic survey, providing baseline data representing all Canadians except the 3% not living in households.  The anthropometric and performance data was then used as the normative data for the Canadian Standardized Test of Fitness

4 C.S.T.F.  Canadian Standardized Test of Fitness  Performance Tests  Step test, grip strength, push ups, sit ups, sit and reach.  Anthropometric Assessment consisted of:  % body Fat determined by the Durnin & Womersley equations based upon the sum of 4 skinfolds (Triceps, Subscapular, Biceps, and Iliac Crest)

5 Durnin & Womersley (1974) Density = a (log 10 Sum 4 SF) + c ◦ Sum of Triceps, Subscapular, Biceps, and Iliac Crest Skinfolds ◦ a & c dependent upon age and gender specific equations ◦ British sample measured on the left side of the body % Fat = (4.95/Density)-4.5) x 100 Problems encountered by C.S.T.F. ◦ Overpredicts by 3 - 5% Fat ◦ Upper body sites

6 C.S.T.F.  Canadian Standardized Test of Fitness  Revised Anthropometric Assessment included:  Body Mass Index  Sum 5 Skinfolds  Sum Trunk Skinfolds  Waist to hip girth ratio

7 C.P.A.F.L.A. The Canadian Physical Activity, Fitness & Lifestyle Approach Modification of the C.S.T.F. ◦ Change in style – Rather than using Health Risk Zones, Health Benefit Zones were identified Anthropometric Assessment includes: ◦ Body Mass Index (BMI) ◦ Sum of Five Skinfolds (mm) (SO5S) ◦ Waist Girth (cm) (WG) ◦ Sum of Two Trunk Skinfolds (mm) (SO2S) C.P.A.F.L.A. was taught in BPK 343 now it is C.S.E.P. PATH

8 CSEP-PATH 2013 P hysical A ctivity T raining for H ealth Skinfolds removed Subject embarrassment Measurer training Waist Girth definition changed Girth at the level of the top of the iliac crests Justified as more reliably located and better related to health consequences Requires landmarks

9 Advanced O-SCALE System for individual physique assessment

10 Developed to fill a need  % body fat predictions have unacceptably high S.E.E.’s  Individual assessments vs group validation  Designed with the expectation of becoming obsolete very soon

11 Components  Anthropometric measures  Height, Weight, Skinfolds, Girths, Humerus and Femur width  Geometric scaling  Maintain shape and composition  General appraisal of physique  A and W ratings  Detailed appraisal  Size and Proportionality Profiles

12  STANINE chosen for O-SCALE system based upon number of categories and equal width of categories Stanine Category Percentage of Normal Distribution within Category 4%7%12%17%20%17%12%7%4% Boundary Z-Scores Boundary Percentiles

13 General description of physique  Adiposity rating based on skinfolds  Proportional weight rating  Stanine scores  equal width of categories  nine categories seemed appropriate

14 Adiposity Rating  Proportional Sum of six skinfolds  Sum 6 SF * (170.18/Ht)  Comparison to age and sex specific norms via stanine scale

15 Females 23 year old female Prop. Sum of 6 skinfolds = 79.4 Adiposity (A) rating = 3

16 Proportional Weight Rating  Proportional Weight  WT * (170.18/HT) 3  Comparison to age and sex specific norms via stanine scale

17 Females

18 A & W Ratings  A = 7, W = 7, - Balanced physique  A = 7, W = 5, - Adiposity dominant  A = 5, W = 7, - Weight dominant

20 Detailed Description of Physique  Listing of all measures with 4th, 50th & 96th percentiles  Proportionality profiles  z-values plotted vs similarly scaled norm values

37 Differences from O-SCALE system  Normative Database:  Proportional Values rather than z-values:  Skinfold-adjusted Forearm Girth:  Scaling Height is 170cm rather than cm:  Detailed Description of Physique does not require Computer Software:  C.P.A.F.L.A. Indices shown as percentile charts based upon KIN-Scale norms 37
